david.anastacio thank you SOOOOOOOO much!!! you super star!

No problem, happy to help.

@david.anastacio I got it to work, but only in CPU mode... as son as i try with GPU it does wired stuff.

True, I did notice that. That's most likely a bug on the GPU implementation.

Best,
David.

what does it do in the GPU? maybe a bug worth reporting.

Totally. The cpu is the standard, any deviation from the cpu result is for sure a bug/limitation of the gpu.
I report way too many bugs already, and the gpu stuff is not something we use much, as the data sets we work with are way too large to fit in the gpu, maybe with "out-of-core" in vray 5 that changes a bit.
If this is a thing you would like to see fixed , you should post it in the issues section.

Best,
David.
